Title: Freezing device for transportation
Inventor: JIEFURII BUREIN BAAJI
IPC: F25D29/00
Filed: 1989-12-28
Abstract: PURPOSE: To make the temperature of loading space accurate, by providing the suction pipe of a refrigerant compressor with an adjusting valve which is controlled by a diesel engine and an adjusting control means, with its loading temperature within a specified temperature range. CONSTITUTION: A compressor 14 is driven continuously by a prime mover 16, and at cooling start, it cools air in high-speed cooling mode, and when the air returning from loading space 92 to an evaporator 42 reaches the first specified temperature difference to the objective temperature, it cools the air in low-speed cooling mode until the air reaches the second specified difference temperature. When it reaches the objective value, an adjusting valve 54 provided in a suction pipe 50 is controlled by an adjusting control means 108, answering the signal from a digital thermostat 84.  Then, when the temperature of reflux air shows descent tendency, it switches into heating mode where compressor discharge gas at high temperature commutates from a condenser 24 to the evaporator 42, and an adjusting control means 108 opens the adjusting valve 54 gradually, according to the difference between the reflux air temperature and the objective temperature. When the temperature of the reflux air begins to go up above the objective temperature, the adjusting control means 108 lessens the opening of the adjusting valve 54, and when it begins to go down, the adjusting valve 54 closes gradually again. Hereby, it becomes possible to bring the loading space into an equal temperature close to the objective value, and also, to keep the relative humidity high.
